JOSEPH J. SCHOLFIELD, OF PROVIDENCE, RHODE ISLAND.

PRESSR-WHEEL FOR THE CHAINS 0F CLOTH-DRYING MACHINES.

$PECIFIGATION forming part of Letters Patent No. 743,990, dated November 10, 1903.

Application filed July 31, 1902.

To utZZ whom it may concern:

Be it known that I, JOSEPH J. SoHoLFInLD, a citizen of the United States, and a resident of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Presser-Wheels for the Chains of Cloth-Drying Machines, of which the follow ing is a specification.

Myinvention consists in the improved con struction of the presser-Wheel and its operative combination with the spur-links of the chain, as hereinafter set forth.

In the accompanying drawings, Figure 1 represents a side view of my improved presser wheel, also showing a side view of the sprocket-wheel and a partial side view of the chain, the presser-wheel being shown in engagement with the spurs of the chain. Fig. 2 represents a top view of the same. Fig. 3 represents a side view showing the presse rwheel raised from the spurs of the chain. Fig. 4 represents an enlarged partial side view of the presser-wheel with one of the protecting side plates removed. Fig. 5 represents a section taken on the line 5 5 of Fig. 4. Fig. 6 represents a side view, and Fig. 7 an edge view, of the eccentric for raising and lowering the resser-wheel. Fig. 8 represents an enlarged side view of the spurs of the chain. Fig. 9 represents a modified form of construction for pressing the spurs. Fig. 10 represents an axial section of a presserwheel embodying this latter form of the invention.

In the drawings, A represents a portion of the ordinary spur-chain of a cloth-drying machine, and B the sprocket-wheel by means of which it is driven.

0 represents an end portion of the supporting-frame, and D the standard arranged for supporting the presser-wheel E, the said wheel being formed of a central disk F,which may be made of wood or other suitable material placed within the metallic ring G, in which are thickly-set the radially-directed pins on a, provided with the bluntly-pointed ends 6 b, which serve to press the cloth down onto the slender engaging spurs c c of the chain A, and'the protectingdisks H H, which fierial No. 117,867. (N0 model.)

serve to protect the points of the pins or, a,

from injury, are secured to the sides of the core F by means of screws Q.

The presser-wheel E is mounted uponvtlie stud I, which projects ecceutrically from the side of the disk J, the said disk being provided at its edge with the operating-handle K. The disk J is held loosely upon the head L of the stud M by means of the annular flange N, which is secured to the disk J by means of screws, and the stud M is firmly held in the supporting-standard D. The disk J is provided with the stop e, and upon the handleK is mounted the stop f, the said stops serving to limit the extent of movement of the handle K in raising or lowering the presser' wheel from and to the spurs of the chain. When the cloth-drying machine is set in operation,the selvages of the cloth will be drawn along by means of suitable mechanism and pressed down upon the slender spurs c c of the chain A by means of the stouter or less tapering pins a a of the presser-whee'l. The pins a a are to be arranged in circumferential rows, as shown in Fig. 2, which is a feature of my invention.

Instead of inserting the pins Ct at of the presser-wheel separately in a ring G as described they may be stamped out at the periphery of a circular disk or segment 0 of sheet metal, as shown in Fig. 9, so as to be integral therewith, and several of these disks or segments may be arranged side by side with intervening washers Pand securely held in position by means of the screws Q, which pass through the perforations g g of the se,,-

ments 0 and through the washers P, in car- I rying out my invention.

' I claim as my invention 1. The combination of the endless spurchain with the presser-wheel provided with a series of rigid pointed pins arranged in circumferential rows and adapted to press the cloth upon the spurs of the chain.

2. The combination of the endless spurchain and the presser-wheel provided with a series of rigid pointed pins arranged in circumferential rows and the eccentric for operating the presser-wheel to engage and disat the side of the wheel for protecting the engage with the fabric which is to be atpoints of the pin from injury.

tached to the spurs of the chain.

3. The combination of the endless s urchain with the presser-wheel provided wi th a JOSEPH SOHOLFIELD' 5 series of rigid pointed pins arranged in circumferential rows, to press the cloth upon the spurs of the chain, and means arranged Witnesses:
